    • Novel compact "via-less" ultra-wide band filter utilizing capacitive microstrip patch 

      Mohammad Shahrazel, Razalli; Alyani, Ismail; Mohamed Adzir, Mahdi; Mohd Nizar, Hamidon (EMW Publishing, 2009)
      This paper presents a novel compact "via-less" UWB filter derived from a quarter-wavelength short-circuited stubs model. In this compact "via-less" UWB filter, there is no connecting vias as short circuit elements. Unlike ...

    • Novel compact microstrip ultra-wideband filter utilizing short-circuited stubs with less vias 

      Mohammad Shahrazel, Razalli; Alyani, Ismail; Mohamed Adzir, Mahdi (EMW Publishing, 2008)
      We present here a new pattern with compact size of Ultra Wideband (UWB) microwave filter. The filter is based on quarter-wave length short-circuited stubs model. We introduced here a new schematic model by extracting all ...

    • "Via-Less” UWB Filter using Patched Microstrip Stubs 

      Mohammad Shahrazel, Razalli; Alyani, Ismail; Mohamed Adzir, Mahdi; Mohd Nizar, Hamidon (VSP (imprint of Brill), 2009)
      This paper presents an Ultra-Wide Band (UWB) microstrip filter which is initially modeled from a quarter-wavelength short-circuited stubs, without the use of any vias. All vias that provide short circuit stubs are replaced ...

    • X-band trisection substrate-integrated waveguide quasi-elliptic filter 

      Alyani, Ismail; Mohammad Shahrazel, Razalli; Mohamed Adzir, Mahdi; Abdullah, R.S.A.R; Noordin, N.K; Rasid, M.F.A (EMW Publishing, 2008)
      A narrowband trisection substrate-integrated waveguide elliptic filter with coplanar waveguide (CPW) input and output ports is proposed and demonstrated for X-band applications. The filter is formed by incorporating ...
